Track kudos of arbitrary words

[jcraigk]

Sometimes people like to give or remove kudos from random words that are relevant to their work like pianos ++ or javascript --. Currently KudoChest will ignore this because it does not contain a keyword like username, channel, etc.

Ideas:

• Make this globally optional via App Settings (on/off)
• Admin should be able to browse/edit/delete the words that have already been upvoted/downvoted
• Include the words in export to csv?
• Always allow negative numbers (this will be a primary use case) - do not rely on Kudont settings.
• Chat commands only or via Dialog as well?
• Leaderboard for arbitrary words
• Use Redis only or PG to store the totals? Redis would probably be easier/faster. Probably no need for a user to see past tips to these namespaces
• Import feature should include arbitrary words
